CULTIVATOR.

:ESPBCIFICATION forming part of Letters Patent No. 298,828, dated May 20, 1884.

Application filed February 2, 1883. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE W. BROWN, a citizen of the United States, residing at Galesburg, in the county of- Knox and State of Illinois, have invented certain new and useful Improvements in Cultivators; and I do hereby declare the following to-be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to that class of cultivator-couplings in which the plow-gan gs swing laterally on journals or standards, arranged above the horizontal ends of the axles, which ends of the axles constitute journal-bearings for said standards in swinging the plow-gangs vertically.

The principal feature of the invention consists in a draft plate or clevis connected with the upper end of a tubular standard on the beam-plate, which standard turns on a suitable bearing, to permit lateral swing of the plow-gangs, and which draft -plate extends downward forward of the coupling, and is provided with a series of holes, by means of which the draft may be utilized to exert either downward or upward forceon the plows or shovels, or no force at all, as desired, and the draft on which, when the plows are in operation, will resist the tendency of the plow-gangs to turn the couplings on the horizontal ends of the axle.

The invention further consists in constructions and combinations hereinafter described.

In the accompanying drawings, which illustratc my invention, and in which the similar letters of reference apply to like parts in all of the figures, Figure 1 is a side elevation of a cultivator embodying my invention, the near wheel removed, and the distant wheel shown in dotted lines. Fig. 2 is a front elevation of the coupling, the draft-plate shown swung around to one side to show other parts. Fig. 3 is a vertical sectional elevation of the coupling and adjacent parts in line as a: in Fig. 2. Fig. 4 is a top plan of the coupling and adjacent parts.

The general machine in which my improve ments are incorporated need not be further described than to state that.A is an ordinary arched axle, with horizontal ends A, tongue B, double-tree B, with pendant b, to which single-trees b and links I) are attached, and O G are the plow-gangs, with plows c and handles c.

The foregoing parts described by letter may be of any ordinary construction, as my invention is applicable to any cultivator where the coupling is made to a horizontal part of the axle, or other horizontal part of the cultivator.

D is a bolt, with eyes (1 on its lower end, through which eyes the horizontal end A of the axle passes. The eyes (1 and bolt D may be adjusted lengthwise of the arm A, and held after adjustment by a keeper, (1.

E is a hollow standard, which extends nearly to the top of the bolt D, and the lower end of which terminates in projections 6, each of which has a groove, 6, in its lower end, which fit upon the arm A of the axle, and prevent the standard E turning on the bolt D. Near the base of the standard E it is enlarged to form a bearingsurfaee, e.

G isthe beam-plate, fixed to the forward end of the plow beam or gang. The forward end of the plate G carries a hollow standard, G, which fits over the standard E, and rests at its lower end on the bearinge, while its upper endextends a little above the top of the standard E. A11 annular collar or flange, 9, projects from the standard G a short distance from its upper end.

H is the draft-plate, formed of an arm, h, with an eye, h, at one end, which eye fits over and is j ournaled on the standard G, and rests on the collar g. The arm h projects forward from the eye h, and is then bent downwardly and extends below the arm A of the axle. The vertical part of the arm h has a series of holes, it, through it, with either of which a link, b, may be engaged to connect the plate H with the draft, for purposeshereinafter described.

I is a nut, which, when screwed onto the upper end of the bolt D, will secure the parts together. I

J is a cap for holding the nut I from unscrewing, and is itself held from turning by a key, j, which passes through the bolt D, and through groovesin the upper side of cap J I is a washer under the nut I.

In operation, the hollow standard G turns on the standard E, to permit swinging the plow-gangs laterally, and the eyes d and projections e turn 011 the axle-arm A, to permit swinging the gangs vertically, while the long standard E forms a bearing for the extended standard G, and at the same time prevents undue strain on the bolt D. By engaging the links I) in the lower holes h" of the series in the plate H, a part of the force exerted by the draft-animals in drawing the cultivator will be used in forcing the plows downwardly and into the ground, and may thus be utilized in plowing in hard ground, and when it is desired to plow deep in looser soil. By engaging the links I) in the upper holes h, the draft will tend to raise the rear ends of the plows and cause them to run more shallow, and will also aid in manipulating the plows while in operation. By engaging the links Z) with holes centrally in the series, the draft will neither raise nor depress the plow-gangs at their rear ends. In all cases of adjustment of the attachment of the links b higher or lower on the arm It, the draft acting on the upper ends of the bolt D and standards E G will prevent the strain in this class of joints arising from the resistance of the plows acting entirely on one side of the journal A.

The plate H can swing laterally on its bearing on the standard G, as shown by dotted lines at Fig. 4, and hence when the plow-gang is swung laterally the standard G- willturn in the eye h, and not affect the plate H, and the plate H is free to swing to accommodate itself t0 the direction of the draft.

What I claim as new, and desire to secure by Letters Patent, is

1. In a cultivator-coupling, in combination with the bolt D, having eyes d, through which the arm A passes, and long tubular standard E, seatedvon the bolt D, and held by projections 0, which rest on the arm A, the beamplate provided with a tubular standard, G, journaled on the standard E, and nut I for securing the parts together, substantially as and for the purpose specified.

2. The combination,with the plow-beam and axle, eyebolt D, standard E, and beam-plate G, of the draft-plate H, extended forward and downward, and provided with a series of holes for the draft attachment to adjust the draft to exert a downward or an upward force, or not to exert any vertical force upon the beams, substantially as and for the purpose set forth.

3. In combination with the bolt D, journaled on a horizontal part of a cultivator, long tubular standard E, having lugs e, beamplate G, having tubular standard G, journaled on the standard E, the draft-plate H, journaled on the standard G, and provided with holes h, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
